Comments on the geologic information

  • PROSPECT OCCURS IN A FAULT ZONE, EVIDENCED BY THE BRECCIA. THE CRANBERRY GNEISS IS DEEPLY WEATHERED NEAR THE SURFACE AND RELATIVELY FRESH IN THE LOWER PARTS OF THE DEEPER SHAFT. SAMPLES OF ORE ON THE DUMP SHOWED FINE GRAINED, MASSIVE CLUSTERS OF BARITE CRYSTALS OCCASIONALLY VUGGY WITH MINOR IRON STAINING, WITH PINK FELDSPAR AND EPIDOTE CLUSTERS AND MINOR CHLORITE, BIOTITE AND A TRACE OF PYRITE. GRANITE GNEISS FOLIATION TRENDS N27E AND DIPS 50SE.

Economic information about the deposit and operations

Development status Occurrence
Commodity type Non-metallic
Deposit size Small
Significant No
Discovery year 1850

Mining district

District name Gossan Lead District

Land status

Ownership category Private

Ownership information

  • Type Owner
    Owner Dixon, Glen W.
    First year 1986

Comments on the production information

  • FUTURE PRODUCTION IS DOUBTFUL.

Comments on the reserve resource information

  • SMALL QUANTITIES OF BARITE PROBABLY STILL EXIST AT THIS LOCATION, BUT NOT IN SUFFICIENT QUANTITIES TO MAKE IT ECONOMICAL.

Workings at the site

  • Type of workings Surface/Underground
    Length 102M

Comments on the workings information

  • WORKINGS CONSIST OF 3 SHAFTS, ONE ABOUT 30.5M (100FT) DEEP AND ANOTHER ABOUT 11M (35FT) DEEP. EACH HAS A TUNNEL AT THE BOTTOM OF THE SHAFT ABOUT 30.5M (100FT) LONG IN A S35E DIRECTION. ALSO SEVERAL SHALLOW PITS WERE DUG. ONLY ONE SHAFT AND SMALL DUMP WAS LOCATED DURING THE FIELD EXAMINATION CONDUCTED 1/9/86. CAVED SHAFT MEASURED APPROXIMATELY 8X12 FT AND 3 FT DEEP. THE OVERGROWN DUMP MEASURED APPROXIMATELY 20X40 FT ON THE HILLSIDE.

Comments on development

  • PROSPECT WAS WORKED AROUND 1850, BUT SOON ABANDONED. IT WAS REOPENED IN 1926 WHEN 3 SHAFTS AND ASSOCIATED TUNNELS AND SEVERAL OPEN CUTS WERE DUG. NO PRODUCTION OCCURRED. WORKINGS ARE NOW FILLED WITH DEBRIS.

General comments

Subject category Comment text
Deposit BARITE OCCURS IN VEINS AS MUCH AS 0.4M (1.3 FT) WIDE AND AS A CEMENT IN BRECCIA. THE VEINS AND BARITE CEMENTED BRECCIA OCCUR FROM THE SURFACE TO THE BOTTOM OF THE DEEPEST SHAFT, ABOUT 30.5M (100 FT). THE BARITE IS FINE GRAINED AND COMMONLY SHOWS SOME REPLACEMENT AND HYDROTHERMAL ALTERATION OF THE WALL ROCK.
